received a letter from Arthur  Andersen  LLP (Arthur  Andersen)  with respect to
Arthur Andersen's audit of the Company's  consolidated  financial statements for
the year ended February 28, 2002.  Arthur  Andersen's  letter certifies that the

was appropriate  continuity of Arthur Andersen  personnel  working on the audit,
availability of national office  consultation,  and availability of personnel at
foreign  affiliates of Arthur  Andersen to conduct the relevant  portions of the
audit.

Very truly yours,
